When the plot dock was short, Qt Charts dropped the axis labels first, making
the plot hard to read.
- Reclaim Qt Charts' outer graphics-layout padding and trim the inner margins
(both chart views) so the plot and its labels get the available space.
- Raise the chart minimum height (dataset-info 80 -> 140, per-image 120 -> 140)
so the dock can't be squeezed below the point where the axis labels fit.
